There are several reasons why your blood sugar levels may be higher in the morning, says Mr. Denis. First, remember that diabetes mellitus is a progressive disease in which the hormones produced by the body may become inadequate and unable to compensate for blood glucose. In addition, insulin resistance prevents cells from taking glucose effectively.
Now keep in mind that while your body rests physically during the night, your mind does not take breaks - your brain is still very active, as are your organs. At night, your hormones are very busy at work, regenerating and restoring the body from daytime and preparing it to wake up.
For this purpose, a group of hormones is released at around 3-4am, which provides you with the energy you need to wake up - one of the effects of this is glucose in the bloodstream. It's called "Dawn Phenomenon" and increases your FBS sugar levels.
Another possibility is something called the "Somoga Effect". It is when glucose levels drop super low overnight, which activates your emergency backup system, triggers hormones again, and sends messages to your liver and muscles to send sugar to the system, which can bounce back very high. The Somoga Effect is more common with those who take insulin. You can read more about the Dawn Phenomenon and the Somoga Effect here, says Dr. Slinkin. What's more, if you don't sleep well or even have intense sleep, it can also affect hormones. Finally, sometimes medicines that are taken at the beginning of the day (which help maintain good control) may wear out in the morning.
When is the best time to take a dose of blood sugar FBS at your post?
It is best to check your blood sugar level when you stand up.
If you do this as part of your morning routine, for example after you go to the bathroom or brush your teeth, it will be easier to remember. Storing supplies on your nightstand, in the bathroom or in the kitchen - wherever you are - will help you do this. What's the safest way to get a blood sample? Is the side of your finger as good as your palm or anywhere else? Fingertips are the best place to test and get the most accurate readings. The reason for that is because they're the best place to get the final capillaries. You can saw anywhere on your fingertips, but I always recommend using side parts for 2 reasons:
1. Less nerve endings = painless!
2. You have 2 sides on each finger (plus thumbs), so you double the rotation options, leaving your fingers less painful and less chance to build capillaries from pushing.
